This chapter explains how the banking system creates money and increases the money supply. The balance sheets of the banks are used to show how different transactions impact the banks and the money supply. You will learn the difference between excess and required reserves. You will learn how the money multiplier impacts the money supply. Lastly, we will discuss the bank panics of the 1930s.

Fractional Reserve System
The Goldsmiths
Stored gold and gave a receipt
Receipts used as money by public
Made loans by issuing receipts
Characteristics:
Banks create money through lending
Banks are subject to “panics”

The development of a functioning banking system is key to the economic development of any system. Banking developed as early traders recognized that carrying gold around to use in transactions was both unsafe and inconvenient. Goldsmiths would take the gold, store it in a safe place, and give the trader a receipt which could then be used in place of the gold. The trader could give the receipt to another party who could then go to the goldsmith and retrieve the gold.
As the system developed, the goldsmiths discovered that owners rarely actually came back for the gold, so some goldsmiths began issuing excess paper receipts as loans to merchants, producers, and really just about anyone whom they felt would pay back the loan. This was the beginning of the fractional reserve system still in use today. The only way that the system can fail is if every depositor demands their funds back at the same time, causing a run on the bank. Today’s banking system has many safeguards in place to secure deposits and prevent panics from occurring.

In this slide, the bank has actually increased its value by accepting deposits from customers. The deposits are recorded as liabilities of the bank, as the bank must return the money to the customers upon request. The assets of the bank also increase as the bank now has more cash.

Banks are not required to keep 100% of their deposits on hand at all times because the probability that all customers will ask for their money back at the same time is small. If all customers did return to demand their money at the same time, this would be referred to as a “run on the bank.”

In our example, the excess reserves would equal $90,000, which is actual reserves of $110,000 minus the required reserve of $20,000.

Now we are actually creating new money as opposed to just moving around old money. A bank’s loans are its assets. Having someone owe you money is a good thing (having them actually pay you is even better). Here both assets and deposits increased.

Obviously, the events of the past couple of years illustrate the fact that even with the restrictions in place, it is a difficult balancing act for a bank to earn a profit while maintaining sufficient liquidity to handle those periods of lows that naturally occur in the business cycle.

Multiple-deposit expansion

20% required reserves
All banks “loaned up”
Banks lend all of their excess reserves
A $100 bill is found and deposited
Multiple deposits can be created

As the checks of one bank are deposited into another, the illusion of new money exists and leads to even more new money being created.

This table illustrates the creation of new money based on a single $100 deposit made into one bank. Each subsequent bank can lend a smaller portion of $100 after factoring in their reserve requirement, but overall total deposits in all banks will increase.

The money multiplier is a key measure in banking that helps to predict the money supply that will be available to drive economic growth. As you can see from the formula, if the reserve requirement is 20%, the money multiplier will be 1 divided by 0.2, which is 5. We can then use the money multiplier multiplied by the excess reserves to determine the maximum checkable-deposit creation that will be provided by the new money entering the system.

Making loans creates money
Loan repayment destroys money
LO5
Ironically, one of the items that is slowing current economic growth is people paying down credit card balances and other loans; this is, in effect, removing money from the system.
*
Banking, Leverage, and Financial Instability
Leverage is the use of borrowed money to magnify profits and losses
Modern banks use lots of leverage
Thus small losses can drive banks into insolvency
By using leverage, a bank can use borrowed money to invest which leads to greater profits for investors if things go well but increased losses if things go bad. The government in the past has stepped in to bail out banks who made bad investment decisions leading to a moral hazard. If banks do not have to assume the risk of bad decisions, there is no incentive for them to make more conservative decisions in the future. Bankers have lobbied the government against any attempt to require lower leverage levels so the current regulatory system relies on bank supervisors who attempt to prevent the banks from making bad loans. That system was unable to prevent the 2007-2008 financial crisis.
